Integrated pest management program (IPM program) for autumn-winter melon in greenhouse was combined of physical and biological control agents. Availability of IPM program was compared with grower's spray program at commercial greenhouse and the following results were obtained. Soil sterilization using hot water was effective to nematode and root rot. Natural enemy and selective insecticide controlled population of cotton aphis, whitefly, thrips, mite and leafminer. Insect-proof net of 4 mm mesh prevented migration into greenhouse of corn earworm and cotton caterpillar. Consequently, chemical insecticide use was reduced 50%, and that quality and yield of fruits were equal to grower's spray program. However, cost of IPM program was 3 to 9 times as grower's spray program. These results indicate that IPM program available on autumn-winter melon but would be required to reduce its cost.
